Validity and accuracy of swespine data on surgery for central lumbar spinal stenosis and lumbar disc herniation: a cohort study of 796 patients.
Article in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo validate the Swedish National Spine Registry (Swespine) for diagnostic accuracy and documentation of surgical procedures for central lumbar spinal stenosis (CLSS) and lumbar disc herniation (LDH), including an analysis of preoperative magnetic resonance imaging (MRI). Additionally, this study evaluates the accuracy and completeness of perioperative data and documented complications.
methodsOf 41,312 patients registered in Swespine for CLSS or LDH between January 2017 and December 2022, 800 were randomly selected from four hospitals. The electronic patient records were used as the gold standard. Radiological criteria for CLSS and LDH were established through a review of MRI scans.
resultsThe proportion of correctly classified diagnoses (PCC) was 98.5% for CLSS and 99.2% for LDH, while the PCC of the type of surgery was 99.7% and 98.5% in the CLSS and LDH cohorts, respectively. Preoperative MRI analysis showed that 94.2% of patients undergoing CLSS surgery at the narrowest spinal level were classified as Schizas C or D, with a mean cross-sectional area of 44.2 mm². In comparison, 85.0% of patients who underwent LDH surgery were classified with Pfirrman grade 3.
conclusionSwespine demonstrated high accuracy and completeness in diagnosing and surgically treating CLSS and LDH patients, as corroborated by preoperative MRI assessments. Most perioperative data, including complications, demonstrated acceptable to excellent registration. Improvements are recommended in the documentation of the American Society of Anaesthesiologists classification, patient weight and height, smoking status, use of implants and bone grafts, date of discharge, use of thromboprophylaxis, and previous surgeries.
